268 THE MOTHS OF THE BRITISH ISLES. 



powdered with ochreous grey, and the lines are very indistinct. 

 The more usual forms are shown on Plate 107, Figs. 13, 14. 



The caterpillar is green, inclining to yellowish or to brownish ; 

 some purplish-red marks and white-edged black spots on the 

 back; the ring divisions are yellow, and there are reddish- 

 brown or purplish-red marks on the sides ; the markings vary. 

 It feeds on birch, alder, and sallow, and may be beaten out at 

 any time from July to September. The moth is out through 

 the summer from May: its range in the British Isles is very 

 similar to that of the last species, but it seems to have a 

 preference for moist places. 



The distribution abroad extends eastward to Amurland, and 

 a form known as ab. schcefferi^ Bremer, occurs in the last-named 

 country, and also in Corea and Japan. • : 



Barred Umber {Nttmeria pulveraria). 



Pale ochreous or reddish brown freckled with darker ; the 

 central dark reddish brown band is sometimes much narrowed 

 below the middle ; sometimes only the edges of the band are 

 dark, the enclosed space being but little darker than the ground 

 colour, or occasionally tinged with greenish ; one example of 

 the latter and two of the former were reared this year (1908) 

 from larv?e received in July, 1907, from Mr. F. Pope of Exeter; 

 a male specimen bred from the same batch of larvae, but which 

 emerged in August of the year last mentioned, is distinctly 

 tinged v/ith rosy over all the wings ; the narrow band on the 

 hind wings, not usually extended to the front edge, is in this 

 specimen entire, whilst the greenish-banded specimen referred 

 to above is without trace of a band on the hind wings. Two 

 examples which are without locahty, but which, I believe, 

 came from the New Forest, have pale greyish-brown fore wings 

 banded with brown in which there is a tinge of oHve. Two 

 examples of the male are figured on Plate 108. The eggs (Plate
